ESET researchers detail the modus operandi of LightNeuron, a Microsoft Exchange backdoor that leverages a previously unseen persistence mechanism
ESET research uncovers LightNeuron, the first known malware that specifically targets Microsoft Exchange email servers. LightNeuron has two facets: spying on emails and acting as a full-feature backdoor. It is believed to be the work of Turla, one of the oldest and still-active cyberespionage groups. The gang, which focuses on selected high-profile targets, is believed to have used LightNeuron since at least 2014. All this – and more – on WeLiveSecurity.
